I bookmarked this recipe because it calls for ingredients I always have on hand very little sugar. It's almost like a lemon meringue pie and is adapted from an authentic Irish recipe in the cookbook pictured below. I'm a true lemon🍋 lover and buy lemons in bulk and always have them in my refrigerator crisper drawer. Limes, not so much, except in limeade.
